Electronic Device and Method for Noise Alerting

1. An electronic device for noise alerting, comprising: a collecting unit to record ambient sound around the electronic device and generate corresponding sound signals; a volume unit to determine a volume of the ambient sound according to the sound signals; a first storing unit to store a first table mapping relationships between a plurality of volumes and noise grades; a comparing unit to obtain the noise grade corresponding to the determined volume of the ambient sound in the first table; a second storing unit to store a second table mapping relationships between various noise grades and solutions, wherein the solutions alert a user to take appropriate countermeasures to reduce the risk of harm to the user from excessively loud noise in time and are associated with the various noise grades; a calling unit to search the second table in the second storing unit to obtain the solution corresponding to the obtained noise grade of the ambient sound; and an outputting unit to output an alert to a user for recommending the obtained solution.

2. The electronic device according to claim 1 , wherein the electronic device is a mobile phone or a personal digital assistant.

3. The electronic device according to claim 1 , wherein the first storing unit and the second storing unit are independent modules.

4. The electronic device according to claim 1 , wherein the first storing unit and the second storing unit are disposed in one memory divided into different data storage areas.

5. The electronic device according to claim 1 , wherein the outputting unit outputs solutions by lights flashing, a visual alert on a display, audible signals emitted from a speaker, or any combination thereof.

6. A method for noise alerting, comprising: recording ambient sound around an electronic device and generating corresponding sound signals; determining a volume of the ambient sound according to the sound signal; obtaining a noise grade corresponding to the determined volume of the ambient sound in a first table mapping relationships between a plurality of volumes and noise grades; searching a second table mapping relationships between various noise grades and solutions to obtain a solution corresponding to the obtained noise grade of the ambient sound, wherein the solutions alert a user to take appropriate countermeasures to reduce the risk of harm to the user from excessively loud noise in time and are associated with the various noise grades; and outputting an alert to a user for recommending the obtained solution.

7. The method according to claim 6 , wherein the step of outputting the obtained solution is implemented by lights flashing, a visual alert on a display, audible signals emitted from a speaker, or any combination thereof.
